Abstract (en)
[origin: EP2527784A1] The optical measuring method involves illuminating the measurement object (1) surface with a pattern sequence of different optical patterns (2a) by a projector (3). An image sequence of the measuring object surface is recorded with a camera system. The three-dimensional coordinates of the measuring points are determined by evaluating the image sequence. A succession of brightness values for identical measuring points is determined in the respective image of the image sequence. The translational or rotational accelerations of the projector, camera system or the measuring object are measured. An independent claim is included for an optical measuring system for determination of three-dimensional coordinates of multiple measuring points of a measurement object surface.
